Is there a particular pump type which can cope with expelling human hair along with the showerwater?

My wife and daughters all have long hair - beautiful when it's on their heads, but a pain when it clogs up the showerpump strainer. Currently, I find myself having to clean those strainers about twice a week. It is not a particularly arduous job, but I am prepared to invest in a different/better pump if it means I can go significantly longer between pump cleaning chores.

Agree with diaphragm pumps as the best, went to them after impeller, you can also help using a strainer at the drain. Watch your bilge pump, as hair works down into the bilge and will stop the bilge pump, looks like a mouse wrapped around it. Last winter had three women on the boat at the same time...the hair was everywhere. OMG pumps and head. Try to get them to brush outside.

Would a macerator pump be appropriate in this application, or is human hair too fine for it to deal with?

No, hair is unbelievably tough, it will just wrap up in a macerator. My Wife has long, thick hair and it gets everywhere.
I believe a strainer to be the only real workable solution, its what we do as IP head drains have strainers built in
I believe our diaphragm pump would clog if not.
